Hi Frank and Kelvin since I don't know how to make attachments work for the mailing list, here's a text copy of its content:
The XSD: ======== <xsd:schema xmlns="http://www.w3.org/2001/XMLSchema"; targetNamespace="http://abc.com/services"; xmlns:tns="http://abc.com/services"; xmlns:sdo="commonj.sdo" xmlns:sdoJava="commonj.sdo/java" xmlns:sdoXml="commonj.sdo/xml" sdoJava:package="com.abc.services" xmlns:xsd="http://www.w3.org/2001/XMLSchema";> <xsd:import namespace="commonj.sdo" schemaLocation="datagraph.xsd" /> <xsd:complexType name="NestedType"> <xsd:sequence> <xsd:element name="test1" type="xsd:string" /> <xsd:element name="test2" type="xsd:string" /> </xsd:sequence> </xsd:complexType> <xsd:complexType name="MyDataGraph"> <complexContent> <extension base="sdo:BaseDataGraphType"> <xsd:sequence> <xsd:element name="NestedType" type="tns:NestedType" /> </xsd:sequence> </extension> </complexContent> </xsd:complexType> <xsd:complexType name="Input"> <xsd:sequence> <xsd:element name="MyDataGraph" type="tns:MyDataGraph"/> </xsd:sequence> </xsd:complexType> </xsd:schema> The Java Test: ============== package com.abc.services; import java.io.ByteArrayOutputStream; import java.io.IOException; import org.apache.tuscany.sdo.util.SDOUtil; import com.abc.services.impl.TestFactoryImpl; import commonj.sdo.DataGraph; import commonj.sdo.DataObject; import commonj.sdo.Type; import commonj.sdo.helper.XMLHelper; import commonj.sdo.impl.HelperProvider; public class TestABC { public static void main(String[] args) { TestFactory.INSTANCE.register(HelperProvider.getDefaultContext()); NestedType nested; System.out.println("**************** static graph **********************\n"); Input input = TestFactory.INSTANCE.createInput(); MyDataGraph staticGraph = TestFactory.INSTANCE.createMyDataGraph(); nested = TestFactory.INSTANCE.createNestedType(); staticGraph.setNestedType(nested); ((DataObject)nested).set("test1", "test1"); ((DataObject)nested).set("test2", "test2"); staticGraph.getChangeSummary().beginLogging(); ((DataObject)nested).set("test2", "test2_modified"); nested.setTest1("test1_modified"); input.setMyDataGraph(staticGraph); saveGraph(staticGraph); System.out.println("\n\n"); System.out.println("**************** dynamic graph **********************\n"); DataGraph dynamicGraph = SDOUtil.createDataGraph(); Type type = ((TestFactoryImpl)TestFactory.INSTANCE).getNestedType(); nested = (NestedType)dynamicGraph.createRootObject(type); ((DataObject)nested).set("test1", "test1"); ((DataObject)nested).set("test2", "test2"); dynamicGraph.getChangeSummary().beginLogging(); ((DataObject)nested).set("test2", "test2_modified"); nested.setTest1("test1_modified"); saveGraph(dynamicGraph); } /** * @param dataobject */ private static void saveGraph(MyDataGraph dataobject) { ByteArrayOutputStream os = new ByteArrayOutputStream(); try { XMLHelper.INSTANCE.save((DataObject) dataobject, null, "datagraph", os); System.out.println(os.toString()); } catch (IOException e) { e.printStackTrace(); } } /** * @param datagraph */ private static void saveGraph(DataGraph datagraph) { try { ByteArrayOutputStream os = new ByteArrayOutputStream(); SDOUtil.saveDataGraph(datagraph, os, null); System.out.println(os.toString()); } catch (IOException e1) { e1.printStackTrace(); } } } Please note, it's the static graph approach which doesn't seem to record the summary. The dynamic approach using the commonj.sdo.DataGraph works fine.
